CVE-2025-69400
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in ThemeREX Yokoo yokoo allows PHP Local File Inclusion.This issue affects Yokoo: from n/a through <= 1.1.11.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA PHP Local File Inclusion vulnerability exists in the ThemeREX Yokoo theme where user-supplied input is improperly validated before being used in include/require statements. This allows attackers to include arbitrary local files from the server, potentially exposing sensitive configuration files, credentials, or achieving remote code execution if writable directories can be accessed.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm ThemeREX Yokoo theme is installedInspect the theme directory (typically wp-content/themes/ or similar based on your CMS) and verify the presence of the ThemeREX Yokoo theme files. Check theme header files (style.css or functions.php) for theme name declaration.Affected if ThemeREX Yokoo theme files are found in the environment
-
Identify the installed theme versionOpen the theme's style.css or theme config file and locate the version declaration in the header comment. Compare this version against any officially listed affected versions.Affected if The installed version falls within the affected version range or no patched version is documented
-
Locate include/require statements that use user inputSearch theme PHP files for patterns like include($_GET, require($_POST, or similar constructs where request parameters are passed directly to include/require statements without sanitization. Focus on files that handle routing or template loading.Affected if Unsanitized include/require statements using $_GET, $_POST, or $_REQUEST parameters are found in theme files
-
Verify the vulnerable parameter is accessibleTest whether URL parameters used in the include statements can be manipulated through HTTP requests to trigger file inclusion. Attempt to include a known safe file (like /etc/passwd on Linux) to confirm the vulnerability is exploitable.Affected if The parameter accepts arbitrary path input and returns file contents
-
Check PHP configuration for additional risk factorsReview php.ini for allow_url_include=On (enables remote file inclusion) and verify open_basedir restrictions are configured to limit accessible directories.Affected if allow_url_include is enabled or no open_basedir restrictions are set, increasing exploitation severity
If ThemeREX Yokoo theme is installed with a vulnerable version and contains unsanitized include/require statements using user input, the environment is affected by this LFI vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate to a patched version of ThemeREX Yokoo if available; otherwise, implement strict input validation using allowlists for file paths and disable allow_url_include to prevent remote file inclusion. Web Application Firewalls can provide interim protection.
